Since the first edition of this book was published, the packaging industry has undergone many profound changes, including the virtual elimination of cellophane and its replacement with oriented
polypropylene as a carton overwrap, fluid milk in blow-molded HDPE bottles, PET beverage bottles, cookie bags and cartons lined with polyolefin coextrusions instead of waxed glassine, and bread in reclosable polyolefin
and coextruded film bats. How these phrases and ideas have affected the industry and how they will probably alter its course in the future are treated. New concepts of packaging system planning and forecasting
techniques are intruding into package management, and new chapters will introduce them to the reader.
